Furthermore, the signal input terminals and signal output terminals on each side of the substrate are arranged symmetrically about the center of the substrate 10.

[0061] This configuration ensures that regardless of whether the chip 20 rotates 90° or 180° clockwise or counterclockwise, the signal input and output terminals on the top of the substrate 10 are arranged in a set order, facilitating user wiring, avoiding incorrect wiring, and ensuring accurate and quick wiring.

[0062] In other embodiments of this application, chip 20 may also be a white light chip 20 and / or a monochrome chip 20. The monochrome chip 20 may be one of an R chip 21, a G chip 22, or a B chip 23.

[0063] Taking the white light chip 20 as an example, the signal pin group 30 of the LED bead 100 includes a positive signal input terminal and a negative signal output terminal that are electrically connected to the white light chip 20. The substrate 10 in this embodiment has a quadrilateral structure, and each of the four sides of the substrate 10 is provided with a positive signal input terminal and a negative signal output terminal.

[0064] In this embodiment, the LED bead 100 also includes a signal line 40, which includes a positive signal line connected to the positive signal input terminal and a negative signal line connected to the negative signal output terminal. When assembling the LED bead 100, the positive signal input terminal and the negative signal output terminal on any side of the substrate 10 can be selected for circuit connection according to actual needs.

[0065] In other examples of this embodiment, when chip 20 includes a white chip and a monochrome chip, taking monochrome chip R chip 21 as an example, the peripheral side of substrate 10 is provided with a positive signal input terminal, a negative signal output terminal, a first signal input terminal 301 and a first signal output terminal 311.

[0066] Specifically, the positive signal line and the negative signal line can be respectively disposed on two opposite sides of the substrate 10, or the positive signal line and the negative signal line can be respectively disposed on two adjacent sides of the substrate 10, or the positive signal line and the negative signal line can be disposed on the same side of the substrate 10.

[0067] For the LED beads of this application, signal input terminals and signal output terminals are provided on at least two sides of the substrate. When the LED beads are rotated and assembled according to the installation environment, the appropriate signal input terminals and signal output terminals on the substrate can be selected to conduct the circuit of the chip according to the actual product requirements, so as to avoid messy circuit wiring, simplify the assembly of LED beads, thereby optimizing the circuit wiring and installation layout of LED beads, and ensuring the use and assembly of LED beads in different demand environments.

[0068] Although the invention has been described with reference to several typical embodiments, it should be understood that the terminology used is illustrative and exemplary, and not restrictive. Since the invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
